C Specification

The VkBufferCreateInfo structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkBufferCreateInfo {
    VkStructureType        sType;
    const void*            pNext;
    VkBufferCreateFlags    flags;
    VkDeviceSize           size;
    VkBufferUsageFlags     usage;
    VkSharingMode          sharingMode;
    uint32_t               queueFamilyIndexCount;
    const uint32_t*        pQueueFamilyIndices;
} VkBufferCreateInfo;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is a bitmask of VkBufferCreateFlagBits specifying additional parameters of the buffer.

  • size is the size in bytes of the buffer to be created.

  • usage is a bitmask of VkBufferUsageFlagBits specifying allowed usages of the buffer.

  • sharingMode is a VkSharingMode value specifying the sharing mode of the buffer when it will be accessed by multiple queue families.

  • queueFamilyIndexCount is the number of entries in the pQueueFamilyIndices array.

  • pQueueFamilyIndices is a pointer to an array of queue families that will access this buffer. It is ignored if sharingMode is not VK_SHARING_MODE_CONCURRENT.

Description

usage defines the effective usage flags for the buffer. If the pNext chain includes a VkBufferUsageFlags2CreateInfo structure, VkBufferUsageFlags2CreateInfo::usage from that structure is used as the effective usage instead of usage from this structure.
